Abstract

The structure of the (Sr_xCa_1-x)₁₄Cu₂₄O₄₁ series contains both Cu₂O₃ spin-ladder layers and CuO₂ spin chains. Previous measurements on the undoped sample (x = 1) showed all the holes were located on the chains, with the magnetic Cu²⁺ ions on the chain forming a well-defined dimer configuration. We have performed inelastic neutron scattering on a single crystal of the Ca-doped sample Sr_2.5Ca_11.5Cu₂₄O₄₁. The results show that two magnetic states now coexist on the chain, with one hole per formula unit migrating to the ladders.
